I would prefer the UDP Protocol over TCP like in Bedrock edition. Im pretty sure many PVP players would love this. Here is much non sense in the Minecraft protocol and things made to work not to be optimized (deadlines). At our discord we even already have a sticker :mojang_nonsense: which will be used quiet often. I also don't understand Mojang's tactic with packet changes, It sometimes looks like they care about Packets not being broken and being backwards compatible but them sometimes they change the whole Networking system (1.20)
